As an emerging heavy industry enterprise, how to implement innovative mechanisms in the early stages of business development and create an excellent product platform requires not only a strong independent R&D capability but also complementary resources and industrial integration. Recently, Chery Heavy Industries Co., Ltd. held strategic cooperation signing ceremonies with China University of Science and Technology and Anhui Agricultural University. This company, which was founded on globalization, started to create a brand-new platform through the cooperation of schools and enterprises. While gaining important talent resources, it also gained a strong driving force for science and technology.
At the end of October 2011, Chery Heavy Industries teamed up with the National Agricultural Intelligent Equipment Engineering Technology Research Center to establish a "strategic alliance of precision agriculture industry and equipment technology." Less than a month later, it extended the reach of science and technology cooperation to colleges with even greater potential. field. The University of Science and Technology of China is a key university under the Chinese Academy of Sciences. It focuses on cutting-edge science and high-tech research. Anhui Agricultural University is an important talent training and scientific research base in Anhui Province. Many achievements of the two universities need to be transformed into Direct productivity.
In the knowledge-based economy era, companies rely solely on internal resources to carry out high-cost innovation activities, and it is difficult to adapt to rapidly-developing market demands and increasingly fierce corporate competition. Enterprises should increase the role of external creative and external marketization channels to the same level as the internal creative and internal marketization channels under the closed innovation model.
In the cooperation between Chery Heavy Industries and China University of Science and Technology, in addition to co-constructing an open innovation and cooperation platform, and focusing on major technological breakthroughs and management innovations in the process of Chery’s heavy industry development, the two parties will jointly build high-quality talents in addition to collaborative work in the form of projects. With the employment base, China University of Science and Technology will give full play to the advantages of its public affairs institute and its extensive international exchange and provide support for the globalization process of Chery Heavy Industries.
This is a win-win cooperation. China University of Science and Technology's "connections" in international academic exchanges can help Chery Heavy Industries smoothly promote overseas business. At the same time, the high-tech talents cultivated by China University of Science and Technology also have a place to use them. The two sides will actively explore the school-industry joint training of applied high-end talent model, according to the production and operation needs of Chery heavy industry to develop practical issues and practical plans to strengthen the development of talent and the introduction of intelligence work.
In fact, school-enterprise cooperation is the norm in the international community. Some large multinational corporations in Europe and the United States have set up a school-enterprise cooperation department for personnel training. The company teaches its advanced technology, marketing and management concepts to its students in advance. After graduation, students can take up posts quickly. The new products that the school-industry cooperative research and development can also quickly form and enter the market as soon as possible.
At present, domestic school-enterprise cooperation has basically remained at a relatively low level, and many of the cooperation has been limited to simple enterprise training, recruitment of graduates, and technical consultation. Like Chery Heavy Industries and China University of Science and Technology, there are not many examples of deep cooperation. Some industry experts have stated that many companies do not possess core technologies and cannot form close cooperation with research institutes. Production, education, and research cannot effectively integrate and school-enterprise cooperation naturally maintains a low level. Therefore, the company's technology research and development capabilities and talent management capabilities determine whether school-enterprise cooperation is more gold-bearing.
Wang Jinfu, General Manager of Chery Heavy Industry , stated that the principle of Chery's heavy industry selection is that the business has a long enough life cycle and a large enough value space, mainly focusing on urbanization, agricultural modernization, and new energy. "The business we have locked in is in line with the national 'Twelfth Five-Year' industrial plan, which is conducive to the development of Chery's heavy industry industry operations and capital management capabilities, and is conducive to the integration of global resources and the formation of comparative advantages in China."
At present, Chery Heavy Industries has established R&D centers and manufacturing bases in the “Three Kingdoms and Seven Landsâ€. Among them, there are R&D centers in Beijing, Anhui, Wuhu, Anhui, Italy, and Japan. The Italian R&D center mainly conducts the research and development of electronically controlled hydraulic technology and power system technology, while the Japanese R&D center focuses on the tracking and search of Japanese and Korean equipment technologies.
According to Wang Jinfu, Chery Heavy Industries will implement the "three-step" strategy in accordance with the strategic plan, that is, it will become a well-known equipment manufacturing enterprise within 5 years; it will become a well-known and internationally-renowned equipment manufacturing company with a sales income of 10 years. Break through 100 billion yuan; eventually create a world-class mainstream brand of mechanical equipment. While maintaining stability in the domestic market, Chery Heavy Industries will also go out of the country simultaneously to open up the global market.
For a company that puts technology and talent in the first place, relying on the school-enterprise cooperation and talent strategy will contribute to the rapid realization of its industrial vision. In fact, a strong independent development capability is an important force for improving the competitiveness of enterprises.
At present, the five most commonly used thermosetting plastics in various fields are PU, epoxy resin (EP), silicone, unsaturated polyester (UP) and phenolic resin (PF).
Thermosetting plastic has the following advantages:
Thermosetting plastic has a large rigidity and is extremely elastic and plastic deformation.The temperature has little influence on stiffness, and under the same load and temperature, the creep variable is much smaller than thermoplastic.Good heat resistance;The plastic parts are quite stable when heated.The size of the plastic parts is good. Thermosetting plastic is less affected by temperature and humidity, and Thermosetting plastic can be reduced after forming, making Thermosetting plastic easy to make plastic parts with high precision than thermoplastic ruler.Excellent electrical performance.Resistance to arc and voltage, etc.Good corrosion resistance, weak acid, weak base and organic solvents;Good processability, can be processed by various molding methods and other advantages.
Most thermosetting plastics have the following characteristics:
(1) excellent chemical resistance.
(2) it is usually brittle hard plastic, which can be filled with various fillers to form composite materials.
(3) compared with thermoplastic resin, the molding cycle is longer.
(4) all kinds of modification can be carried out, depending on the combination of resin, crosslinking agent, additive, etc., which can form composite materials with different properties.
(5) good heat resistance, the use of high temperature, Tg of thermosetting polyimide (PI) is about 350 ℃.
(6) can be used as raw materials to meet the application of various fields.Only 5% is used as injection molding material.
(7) the waste is generally used as filler after pulverization, which is difficult to recycle and pollutes the environment.
Due to the high heat resistance of thermosetting plastic, good dimensional stability, good line performance, anti-aging properties are better than thermoplastic plastic and low price, so it is widely used.The disadvantage is that the mechanical properties are poor and need to be enhanced.
It is mainly composed of thermosetting resins, which are involved in various necessary additives to form the plastic of the products.In the process of manufacturing or forming, the liquid will be liquid, which will not melt after curing or melt or soften again.Common thermosetting plastics include phenolic plastic, epoxy plastic, amino plastic, unsaturated polyester, alkyd plastics, etc.Thermosetting plastic and thermoplastic plastics constitute two major components of synthetic plastic.
Thermosetting plastic heating for the first time can soften the flow, heated to a certain temperature, react a crosslinking reaction and curing hardens, this change is irreversible, since then, heating again, already no longer soft flow.It is the use of this characteristic to make the molding process, using the plasticization flow of the initial heating, filling the cavity under pressure, and solidifying to become the product that determines the shape and size.
Thermosetting plastic is distinguished by a chemical reaction that is hardened by heating, pressing or adding the hardener at a definite temperature.After hardening, plastic chemical structure changes, the texture is hard, dissolves in the solvent, heating also no longer softens, if the temperature is too high then decompose.In thermoplastic plastic, the chains of resin molecules are linear or branched, and there is not any chemical bond between the molecular chains, which soften the flow when heated.The process of cooling and hardening is a physical change.
Formaldehyde cross linked plastic includes phenolic plastic, amino plastic (such as urea-formaldehyde - melamine - formaldehyde, etc.).Other cross linked types of plastic include unsaturated polyester, epoxy resin, prevalence, diallyl ester resin, etc.
The commonly used thermosetting plastics are phenolic resin, urea-formaldehyde resin, melamine resin, unsaturated polyester resin, epoxy resin, silicone resin, polyurethane, etc.
Production:Phenolic resin PF (Bakelite sheet)
Phenolic resin is a part of the longest plastic varieties in history, commonly known as bakelite or electric wood, and the appearance is yellowish or black, which is the typical representative of thermosetting plastic.Bakelite sheet molding often use a variety of filling materials, according to different filling materials used, the product performance is also different, Bakelite sheet as molding material, mainly used in the field of need heat resistance, but also as a bonding agent used in plywood, grinding wheel and the brake pads.
